Title: Method and apparatus for the recovery of amines from amine containing exhaust air
IPC: B22C9/12
Filed: 1982-02-04
Abstract: Amine-carrying exhaust air, for example from foundries, is washed in exhaust air purification plants with wash solutions. For the purpose of the recovery of the amines required in foundries, saving of raw materials and reduction of waste water quantities in a first method stage the amine-carrying exhaust air is converted to ammonium phosphate by the use of a wash solution containing a phosphoric acid, the ammonium phosphate solution is mixed in a second method stage with calcium oxide and/or calcium hydroxide with agitation and gentle heat, gaseous amines thereby released are withdrawn and the calcium phosphate produced is separated off and dried. In a third method stage gaseous amines are condensed. The corresponding apparatus for carrying out of this method includes, together with the exhaust air wet washer provided upstream (not shown) a reactor (1) for the production of the gaseous amines and a calcium phosphate suspension, a distillation column (3) for separating the amines, and means (8,9) for the filtration and drying of the calcium phosphate suspension.

Title: Switchable permanent magnetic holding device
Inventor: BAERMANN HORST
IPC: H01F7/20
Filed: 1983-06-03
Abstract: A permanent magnet energized holding device for holding of, or onto, ferromagnetic objects 13 and readily switchable between "on" and "off" positions, has outer and inner cup- shaped pole shoe members (1, 2) of good magnetically conductive material concentrically nested in spaced apart relation one inside the other with their rim edges or pole faces (11, 12) lying in a common plane. A ring-shaped stationary permanent magnet (7) is fixed in the space between the peripheral side walls (5, 6) of the cup members, and the cup members and stationary magnet are correspondingly divided magnetically into two portions at the same points therearound by non- magnetic mediums. A rotatable permanent magnet (10) sandwiched between the base walls (8, 9) of the cup members is rotatable therebetween by an operating shaft or other actuating means to switch the holding device between its "on" and "off" positions. In one rotative position of the rotatable magnet 10 the magnetic polarity thereof coincides with that of the stationary magnet 7 and reinforces the magnetic force thereof so as to increase the magnetic flux in the respective pole shoe members, while in another rotative position its magnetic polarity is in opposition to the magnetic polarity of the stationary magnet and reduces the magnetic flux in the pole shoe members of the device. <IMAGE>

Title: Motor vehicle door assembly
Inventor: CAMPBELL ALAN ALEXANDER
IPC: B60J5/04
Filed: 1983-11-12
Abstract: Assembly is such that the door outer panel 28 is only fitted to the door as a last stage in manufacture, and before such mounting the internal door components are fastened onto the door inner panel 14 from the "outside" of the door. The outer panel 28 is then simply a skin, and can be made from a plastics material. The outer panel is the only part which really needs to be coloured to match the vehicle body, and the rest of the door assembly can then be painted a standard colour, to facilitate overall vehicle assembly. As a result of this possibility, vehicles and doors for the vehicle can be assembled separately, only being brought together towards the end of overall vehicle assembly. <IMAGE>

Title: Improved load carrying platform or pallet
Inventor: BLATCHFORD MICHAEL IAN
IPC: B65D19/12
Filed: 1983-11-15
Abstract: A rectangular platform or pallet (1) of standard size (Figure 5) has side girders (1A), end girders (1B), transverse beams (1B), decking (3), and corner fittings (2) for attachment of lifting tackle. Near each corner a respective leg (4) is swingably mounted by an axle (5) journalled in a side girder (1A) and a bracket (6). The legs can be moved from a horizontal stowed position within the confines of the platform to a horizontal position in which each leg is clear of the platform. From that position the legs can be turned down, about the axis of the axle, to a vertical position. Each leg has spigots (8) and each leg is open at its free-end. Thus the vertical legs of an upper platform can be stood on spigots of the horizontal legs of a lower platform to form a stack of platforms. <IMAGE>

Abstract: A nonionic emulsifier useful for forming a stable aqueous emulsion of a hydrocarbyl-substituted succinic anhydride is the reaction product of:   (a) a hydrocarbyl-substituted succinic anhydride having from 6 to 50 carbon atoms in the hydrocarbyl substituent; and (b) a nonionic water-soluble compound having from 1 to 3 reactive polar groups, said water-soluble compound having sufficient hydrophilic strength to give a balanced oil-in-water emulsifier; wherein the emulsifier so produced contains a free carboxyl group and a substituted carboxyl group per each reacted anhydride molecule.   Aqueous emulsions formed from hydrocarbyl-substituted succinic anhydrides and the nonionic emulsifier can be used to render surfaces water repellent and in particular can be used as sizing agents for cellulose stocks in the production of paper.

Title: Process for the purifying Claus tail gas
Inventor: LELL RAINER
IPC: B01D53/86
Filed: 1984-03-08
Abstract: The invention relates to a process for purifying Claus tail gas by catalytic reduction of the said gas with formation of hydrogen sulphide, cooling of the gas, condensing and separating water from the exhaust gas, adjusting the H2S/SO2 ratio necessary for the further Claus reaction by combining the tail gas with an SO2- containing gas produced by combustion and conducting the combined gases through a first Claus catalyst stage below the sulphur dew point. The process is characterised in that the SO2- containing gas produced by combustion is cooled to a regeneration temperature or cooling temperature and conducted through the second catalyst stage charged with sulphur or respectively freed from sulphur and thereby regenerates or cools the said stage, the sulphur taken up in the regeneration phase is condensed out and separated from the SO2-containing gas by cooling and the SO2-containing gas, after being combined with the tail gas, is conducted through the first catalyst stage for the formation and separation of sulphur.
